Abstract
The utility model belongs to the field of medical instruments, in particular to a lateral ventricle drainage tube which can be used for injecting drugs in intraventricular hemorrhage. The lateral ventricle drainage tube is composed of a drainage tube (2), one end of which is provided with a front side port (6) and a back side port (5), and the other end thereof is equipped with a drainage mouth (1), wherein, the inner wall of the drainage tube is provided with a drug injecting conduit (3), and a drug injecting outlet (7) at one end of the drug injecting conduit (3) passes through the drainage tube (2) between the front side port (6) and the back side port (5) and is communicated with the exterior, the other end of the drug injecting conduit (3) is arranged at the exterior of the drainage tube (2) at the drainage mouth (1) end and is provided with a check valve (8) and a drug injecting mouth (9), and the end of the drug injecting mouth is provided with a heparin cap (10). The lateral ventricle drainage tube of the utility model can inject drugs separately, thus avoiding repeated separation of the joint of the drainage tube and the increment of infection risks; the application thereof is convenient, liquid medicines can flow along a single direction, and the backflow of liquid medicines can be effectively prevented, thus avoiding the damage to the drainage tube caused by repeatedly clamping the drainage tube, reducing cost and relieving the workload of medical care personnel.
Description
Technical field
This utility model belongs to medical apparatus and instruments, but is used in particular for the tricorn drainage tube of a kind of injection that intraventricular hemorrhage uses.
Background technology
At present, neurosurgery often runs into intraventricular hemorrhage clinically needs lateral cerebral ventricle puncture catheter drainage hematoma, in order to dissolve hematoma, often will inject urokinase or streptokinase.But there is following shortcoming in the ventricular drainage tube that uses at present: 1, drainage tube is single chamber, will disconnect drain during injection, behind the injection medicine, connects the drainage pipe drain again, and it is very inconvenient to operate like this, and causes intracranial infection easily.2, need folder to close drainage tube before the injection, decontrol during injection, press from both sides after the injection again and close, frequent so operation easily causes medicinal liquid to backflow.Also increased simultaneously medical personnel's workload.
Summary of the invention
But that to be design a kind of is simple in structure, easy to use for the purpose of this utility model, the tricorn drainage tube of a kind of injection that cost is low.
The purpose of this utility model is achieved in that it is to be made of drainage tube, one end of drainage tube is provided with front-side holes and back side opening, the other end is provided with draining hole, on the inwall of drainage tube, be provided with injection catheter, one end of injection catheter passes drainage tube and the exterior between the forward and backward side opening, the other end is located at the outside of the drainage tube of draining hole end, and is provided with check valve and medicine-pouring port, is provided with calparine cap at the medicine-pouring port end.
This utility model can inject medicine separately owing to be provided with injection catheter on the inwall of drainage tube, also can connect micro pump and continue injection, has avoided repeatedly separately the drainage tube joint and increases infection chance, should use easily.Be provided with check valve at the injection catheter place and make the medicinal liquid one-way flow, prevent that effectively medicinal liquid from backflowing, avoided pressing from both sides repeatedly closing drainage tube, cause drainage tube to damage.Reduce cost, also alleviated medical personnel's workload simultaneously.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing: 1-draining hole, 2-drainage tube, 3-injection catheter, 4-scale, side opening behind the 5-, 6-front-side holes, 7-injection outlet, 8-check valve, 9-medicine-pouring port, 10-calparine cap.
The specific embodiment
That the utility model is described in further detail is as follows below in conjunction with accompanying drawing:
This utility model is to be made of drainage tube 2, one end of drainage tube 2 is provided with front-side holes 6 and back side opening 5, the other end is provided with draining hole 1, on the inwall of drainage tube 2, be provided with injection catheter 3, drainage tube 2 and the exterior between front-side holes 6, the back side opening 5 passed in the one end injection outlet 7 of injection catheter 3, and the other end is located at the outside of the drainage tube 2 of draining hole 1 end, and is provided with check valve 8 and medicine-pouring port 9, be provided with calparine cap 10 at medicine-pouring port 9 ends, be provided with scale 4 at the leading portion of drainage tube 2.
But this utility model is simple in structure, easy to use, cost is low is the tricorn drainage tube that a kind of intraventricular hemorrhage needs the injection that lateral cerebral ventricle puncture catheter drainage hematoma uses.
